The specific shape of the rotating portion 11 is not limited as long as the gas mist forming substrate 20 can be placed. In this embodiment, the rotating part 11 is the cavity, and the rotating part 11 is whole to be the tube-shape, has and holds chamber 11a, in other embodiments, can be other shapes, for example has a disk body, and the disk body epirelief is equipped with two clamping parts, through clamping part centre gripping aerial fog formation base member to aerial fog formation base member also can place on the rotating part.

When the user sucks the mist, the mist-forming base 20 is placed in the housing cavity 11a of the rotary portion 11, and the heating body 30 is inserted into the mist-forming base 20. When the rotary part 11 is in the first position, the gas mist forming base body 20 is in contact with the heating body 30, the gas mist forming base body 20 has a first axial position relative to the heating body 30, and the heating body 30 is controlled to heat the gas mist forming base body 20 to generate gas mist for the user to inhale.

In the process of the rotating part 11 from the first position to the second position, the aerosol-forming substrate 20 is in contact with and kept connected with the heating body 30, and the aerosol-forming substrate 20 and the heating body 30 can generate relative movement in the circumferential direction (shown in the direction Z in fig. 1); in the second position, the aerosol-forming substrate 20 has a second axial position relative to the heating body 30, the first and second axial positions being the same. Preferably, the aerosol-forming substrate and the heating body are not moved axially relative to each other from the first position to the second position.

That is, in both the first and second positions, the aerosol-forming substrate 20 is in contact with the heating body 30 and has no relative movement in the axial direction. Aerial fog forms the in-process of base member 20 and heating member 30 at circumference production relative motion, and aerial fog forms base member 20 and heating member 30 becomes to loosen by the adhesion and takes off, and the user can easily extract aerial fog from heating member 30 and form base member 20, convenient to use, the user of also being convenient for is to the cleanness of aerial fog generating device.

Meanwhile, since the heating body 30 and the mist forming substrate 20 are relatively moved in the circumferential direction, there is no relative movement in the axial direction. Can avoid the rotating part 11 to exert axial force to the heating member 30 at rotatory in-process, be favorable to the stability that heating member 30 and aerial fog generating device are connected, prolong the life of heating member 30.

In addition, the heating body 30 and the mist forming base 20 are relatively moved in the circumferential direction, and there is no relative movement in the axial direction, so that the contact between the high temperature part of the heating body 30 (the tip part of the heating body 30) and the release mechanism can be avoided, the aging of the release mechanism can be delayed, and the service life of the release mechanism can be prolonged.

In other embodiments, the first axial position and the second axial position are different, and during rotation of the rotary part 11 relative to the aerosol-generating device, the aerosol-forming substrate 20 is in contact with the heating body 30, both moving circumferentially and also axially; as long as the aerosol-forming substrate 20 and the heating body 30 can make relative movement in the circumferential direction in the process from the first position to the second position, and the aerosol-forming substrate 20 is in contact with the heating body 30.

In addition, in the present embodiment, in the process of switching the rotating portion 11 from the first position to the second position, the rotating portion 11 rotates in the circumferential direction, and the heating body 30 remains stationary; in other embodiments, the heating body rotates in the circumferential direction, the rotary part 11 remaining stationary, as long as in the second position the aerosol-forming substrate 20 and the heating body 30 produce a relative movement in the circumferential direction. When the heating body rotates along the circumferential direction, the heating body can synchronously rotate along with the aerosol generating device, or the heating body can rotate, and the aerosol generating device where the heating body is located keeps static.

In addition, the specific type of the aerosol-forming substrate 20 of the present invention is not limited as long as it can be heated by the heating body 30 to generate aerosol for the user to suck. During heating of the aerosol-forming substrate 20 by the heating body 30, the aerosol-forming substrate 20 can be heated without burning. For example, in this embodiment, the aerosol-forming substrate 20 is a solid aerosol-forming substrate containing a tobacco component, and the aerosol-forming substrate 20 is surrounded by an outer wrapper (e.g., an aluminum foil layer).

In addition, the specific shape of the heating body 30 is not limited, and the heating body 30 is in a column shape and has a circular cross section in the present embodiment.

The outer package of the gas mist forming base body 20 is prevented from rotating synchronously with the rotating portion 11 in the circumferential direction, and the gas mist forming base body 20 is prevented from rotating asynchronously. Thus, the radial compressive force on the aerosol-forming substrate 20 facilitates relative movement of the aerosol-forming substrate 20 and the heating body 30.
